Filter by:Infants in the neonatal intensive care unit (NICU) may be lost due to risks such as being sensitive, frequent exposure to birth complications and being prone to infection. The most common causes of mortality in newborn babies in the world; Complications due to preterm delivery (28%), infections (26%) and perinatal asphyxia (23%) were reported. Respiratory problems are observed in 4-6% of newborns. These problems are also important causes of mortality in the neonatal period. Newborn infants are more likely to have respiratory distress due to difficulties in airway calibration, few collateral airways, flexible chest wall, poor airway stability, and low functional residual capacity.Invasive mechanical ventilation (IMV) is frequently used in the treatment of newborns with respiratory failure. Various ventilation modes and strategies are used to optimize mechanical ventilation and prevent ventilator-induced lung injury. Among the important issues to be considered in newborns connected to mechanical ventilator (MV); Choosing an appropriately sized endotracheal tube to reduce airway resistance and minimize respiratory workload, correct positioning, regular nursing care, chest physiotherapy, sedation-analgesia, and infection prevention are also included.
The aim of this study is to investigate the relationship between cerebral and peripheral oxygenation and oxygen extraction, as measured by NIRS (near-infrared spectroscopy ), and the FHbF (fraction of fetal hemoglobin) and absolute HbF (fetal hemoglobin) concentration in postnatal conditions in term and preterm neonates.
Patients with COVID-19 and hypoxaemic respiratory failure and admitted to the intensive care unit (ICU) are treated with supplementary oxygen as a standard. However, quality of quantity evidence regarding this practise is low. The aim of the HOT-COVID trial is to evaluate the benefits and harms of two targets of partial pressure of oxygen in arterial blood (PaO2) in guiding the oxygen therapy in acutely ill adult COVID-19 patients with hypoxaemic respiratory failure at ICU admission.
There is a high risk of transmission of COVID-19 to healthcare workers. In a recent cohort, 29% of the patients hospitalized were healthcare workers. Among the WHO's primary strategic objectives for the response to COVID-19, the first was to limit human-to-human transmission, including reducing secondary infections among close contacts and health care workers. Automated oxygen titration, weaning and monitoring (FreeO2 device) may be a solution to reduce the number of interventions of healthcare workers related to oxygen therapy, to reduce complications related to oxygen and to improve monitoring.
The main objective is to evaluate the FreeO2 device combined with noninvasive respiratory support technique for COPD patients and postoperative bariatric surgery patients. The main hypothesis is that FreeO2 device for oxygen therapy associated with NIV or nasal high flow oxygen therapy (NHFOT) allows to reach better oxygenation and avoid hypoxemia and hyperoxia.
During surgery high concentrations of supplementary oxygen are routinely administrated. However, there is increasing evidence of potential harm with liberal oxygen therapy. The hypothesis of the present study is that oxygen therapy adjusted to a normal arterial oxygen target is feasible and will attenuate the side effects of supplementary oxygen therapy. The study design is a before-and-after study in which 25 patients will follow the standard regime with high concentrations of oxygen therapy and 25 patients will be treated with oxygen to achieve a normal value of arterial oxygenation.
This is a prospective multicenter observational trial. Included patients and attending physician complete a standardized questionnaire.
The aim of this study is to evaluate if automated adjustment of oxygen (with FreeO2 device) can reduce the hospital length of stay for acute exacerbation of COPD with comparison of manual oxygen titration.
The objective of this study is to conduct an observational pre/post study to evaluate the clinical impact oxygen guideline implementation on oxygen utilization and oxygenation in critically ill trauma patients.
Prospective analysis included patients, 18 years or older, scheduled for 60 daily HBOT sessions between 2016-2018. Each session was 90 min of 100% oxygen at 2 ATA with 5 minutes air breaks every 20 min, five days per week. Pulmonary functions,measured at baseline and after HBOT,included forced vital capacity (FVC), forced expiratory volume in one second (FEV1), peak expiratory flow rate (PEF).
